“I placed the really small HD3s on top of the JBLs, which positioned them almost perfectly at ear-level, and the sound was nothing less than remarkable right out-of-the-box! Whereas, with the HD6s, I felt their performance was constrained by the wireless function, I did not feel that at all with the HD3s—via Bluetooth, they sounded amazing. I had zero qualms with the sound quality, and was, in fact, mightily impressed that such room-filling sound came from these diminutive little babies. They really sang out, and excelled with virtually any genre of music. I’d been digging all the new music finds I’d been collecting over the last few months over the headphone setup, but what an eye-opener to hear it all through really great speakers. The HD6s are game-changers, but the HD3s are totally remarkable speakers in their own right, capable of producing a really big, satisfying sound like I’d never have believed. My main point here is that whatever the choice of audio input into the HD3s, the results were uniformly superb. The HD3s are very, very highly recommended!” —— positive-feedback.com
